PROXIMITY SOUNDINGS/MODELS SUGGEST THAT MSTR/ INSTABILITY IS SUFFICIENT FOR CONVECTION TDA...TRIGGERED BY THE SEA BRZ. WATER VAPOR/STREAMLINES DEPICT AN UPPER LOW/VORTICITY MAX JUST NORTH OF THE CWFA WHICH MAY PROVIDE ADDITIONAL FORCING FOR CONVECTION OVR THE NERN CWFA. YET...INCREASING SUBSIDENCE (BASED ON GFS/NAM 700-300MB Q-VECTOR DIVERGENCE) EXPECTED OVR THE REGION TDA. WL COMPROMISE BY LOWERING POPS OVR THE NERN CWFA YET RETAINING A CHANCE FOR CONVECTION. BASED ON THE CRP BRN VALUE THIS MORNING (BASED ON 12Z CRP SOUNDING)/EXPECTED SIGNIFICANT VERTICAL SHEAR THIS AFTN...ANTICIPATE MULTICELLS WITH MESOCYCLONES. A SUPERCELL COULD ALSO OCCUR. PREV DISCUSSION... /ISSUED 654 AM CDT SUN MAY 24 2009/ DISCUSSION...SEE THE AVIATION DISCUSSION BELOW FOR MORE DETAILS. AVIATION...PATCHY MVFR CONDITIONS WL PERSIST UNTIL 15Z THIS MORNING ACROSS THE RIO GRANDE RGN. OTHERWISE...VFR CONDITIONS WL PREVAIL ACROSS MOST OF THE REMAINDER OF SOUTH TX TDA. HOWEVER...MVFR AND EVEN BRIEF IFR CONDITIONS WL BE POSSIBLE IN THE VICINITY OF SHOWERS AND THUNDERSTORMS. MOST OF THE SHOWERS AND THUNDERSTORMS WL DEVELOP BETWEEN 18Z AND 02Z TDA...MAINLY EAST OF AN ALICE TO BEEVILLE LINE. VFR CONDITIONS WL THEN PREVAIL AFTER THE STORMS DISSIPATE. PATCHY MVFR STRATUS AND/OR FOG WL BE POSSIBLE BETWEEN 10Z AND 15Z MONDAY ACROSS INTERIOR PORTIONS OF THE COASTAL BEND...MAINLY THE ALI TO VCT CORRIDOR. WITH DRIER CONDITIONS EXPECTED ON MONDAY...LESS SHOWERS AND THUNDERSTORMS ARE EXPECTED TO DEVELOP ON THE SEABREEZE. AS A RESULT...MORE WIDESPREAD VFR CONDITIONS ARE EXPECTED ON MONDAY. PREV DISCUSSION... /ISSUED 326 AM CDT SUN MAY 24 2009/ SHORT TERM (TODAY THROUGH MONDAY)...ANOTHER ACTIVE DAY IS EXPECTED TDA...ESPECIALLY ACROSS THE ERN AREAS. PWS WL AVERAGE AROUND 1.5 INCHES ALONG WITH AN UNCAPPED AIRMASS. A LANDBREEZE CIRCULATION WL TRANSITION INTO A WK SEABREEZE THIS AFTN. THIS WL SIGNIFICANTLY ENHANCE THE MOISTURE CONVERGENCE IN THE BOUNDARY LAYER TDA. MEANWHILE...A WELL-DEFINED VORT MAX WAS MOVING EAST-SOUTHEAST ACROSS THE DRT AREA. THIS VORT MAX WL MOVE SEWD THROUGH THIS EVENING ALONG AN ELONGATED SHEAR AXIS WHICH EXTENDS FROM THE BIG BEND RGN INTO THE NORTHEAST COASTAL BEND. ALL OF THIS LEADS TO THE HIGHEST POPS ACROSS THE NERN AREAS WITH LESSER POPS ACROSS THE RIO GRANDE RGN. VERY UNSTABLE CONDITIONS ALONG WITH MARGINAL WIND SHEAR WL PRODUCE A FEW STRONG TO SVR STORMS THIS AFTN. AS DRIER AND MORE STABLE CONDITIONS ADVECT INTO THE CWA ON THE BACKSIDE OF THIS WEAKENING SHEAR AXIS TNT...CONVECTIVE CHANCES WL BECOME INCREASINGLY STUNTED. ALSO...SLY/SWLY BOUNDARY FLOW WL BE INCREASING TNT AND WL BEGIN TO INCREASE THE CAP...THUS FURTHER LIMITING PCPN TNT. WL STILL KEEP LOWISH POPS FOR TNT ACROSS PRIMARILY THE NERN AREAS GIVEN THE PROXIMITY TO THE SHEAR AXIS...BETTER MOISTURE AND WEAKER CAP. CONVECTION WL BE MUCH MORE ISOALTED ON MONDAY AS THE MOISTURE CONTINUES TO THIN OUT AND THE CAP CONTINUES TO STRENGTHEN. WL ONLY GO WITH SLIGHT CHC POPS FOR MAINLY SEABREEZE ACTIVITY FOR MON. WL CONTINUE TO GO SLIGHTLY HIGHER THAN THE GUIDANCE TEMPS...ESPECIALLY ON MON. MINOR TIDAL OVERFLOW WL BE AN ISSUE DURING THE TIME OF HIGH TIDE THIS MORNING. TIDES WERE GENERALLY RUNNING AROUND THREE-QUARTERS OF A FOOT ABOVE NORMAL. WITH THE HIGHEST TIDES OF THE MONTH OCCURING TDA AND MON DUE TO A NEW MOON PHASE...TIDES WL REACH UP TO 2.5 FT MSL EARLY THIS MORNING ALONG PADRE AND MUSTANG ISLANDS. WL THUS MAINTAIN THE CURRENT COASTAL FLOOD ADVISORY. MARINE...A WEAK OFFSHORE FLOW THROUGH THE FIRST PART OF TDA WL GRADUALLY TRANSITION TO A WK ONSHORE FLOW AS THE SEABREEZE CIRCULATION ESTABLISHES ITSELF. ONSHORE FLOW WL THEN PERSIST AND BE MODERATE TO STRONG AT TIMES TNT AND MON. SEAS WL SLOWLY INCREASE BY 1 TO 2 FEET BY MON IN RESPONSE. AVIATION...MOSTLY VFR CONDITIONS ARE EXPECTED THROUGH MON. MVFR AND EVEN BRIEF IFR CONDITIONS WL BE POSSIBLE DURING INTERMITTENT SHOWERS AND THUNDERSTORMS BETWEEN 19Z AND 02Z EACH DAY. MVFR CONDITIONS DUE TO PATCHY STRATUS AND LIGHT FOG WL BE POSSIBLE BETWEEN 09Z AND 13Z MON ACROSS PORTIONS OF THE INLAND COASTAL BEND...MAINLY BETWEEN ALI AND VCT. LONG TERM (MONDAY NIGHT THROUGH SATURDAY)...ABOVE NORMAL TEMPERATURES WILL PERSIST THROUGH THE PERIOD. BROAD MID-LEVEL RIDGING WILL CREST OVER SOUTH TEXAS MONDAY NIGHT AND SHOULD LEAD TO DRY CONDITIONS ACROSS THE REGION THROUGH TUESDAY. THE RIDGE BREAKS DOWN LATE TUESDAY WITH BOTH THE GFS/ECMWF PROGGING A SHORTWAVE MOVING ACROSS MEXICO AND GENERATING CONVECTION ACROSS THE BRUSH COUNTRY TUESDAY NIGHT. ZONAL FLOW ALOFT WEDNESDAY WILL CONTINUE TO GENERATE RIPPLES IN THE UPPER PATTERN THROUGH THE END OF THE WEEK. MEDIUM RANGE MODELS ARE HAVING A DIFFICULT TIME RESOLVING THE TIMING AND POSITIONING OF THESE SHORTWAVES. HOWEVER...THE MODELS DO INDICATE A MOIST/UNCAPPED ENVIRONMENT OVER SOUTH TEXAS DURING THE LATTER HALF OF THE WEEK. GIVEN THE UNCERTAINTY WITH RESPECT TO THE SHORTWAVES AND AMPLE MOISTURE/INSTABILITY IN PLACE...THINK DIURNAL PROCESSES WILL BE THE PRIMARY DRIVER FOR CONVECTION. INDICATED CHANCE POPS ACROSS THE COASTAL PLAINS DURING THE WED-FRI AFTERNOON PERIODS AND PUSHING INTO THE WESTERN BRUSH COUNTRY DURING THE WED-FRI EVENING PERIODS ALONG THE SEA BREEZE. THE GFS/ECMWF PROG DRIER AIR TO FILTER INTO THE REGION FROM THE NORTH BY SATURDAY. KEPT THE FORECAST FOR SATURDAY DRY AREAWIDE AS A RESULT. && .PRELIMINARY POINT TEMPS/POPS...
